For the drive to operate, one of the following field supply
options must be present.
• A Fixed Field Supply
• A Regulated Field Supply
• An Enhanced Field Supply
At power-up if the Regulated Field Supply Card is installed:
1.
P.177 [Field Regulator]
will detect it’s presence and display
either 4, 10 or 20A — the Regulated Field Supply Card’s
rating.
2. The field current control loop shown above operates and
drive parameters P.184 [J20 Fld Loss Det], P.185 [J21 Field
Supply] and P.272 [E-Fld Volts Adj] are ignored.
3. The Regulated Field Loss and Field Economy circuits
become active in place of those used by the Fixed and
Enhanced Field Supply options.
